Apparatus including a circulating chain for conveying photosensitive material

摘要

Apparatus for processing photosensitive material including a guide bar to which one end of the photosensitive material such as a film strip is attached, a circulating chain which carries the guide bar and which is grasped by a link plate, and a rachet wheel which delivers the guide bar between the rachet wheel and the circulating chain. The rachet wheel is mounted on a drive therefor through an elastic material so that the torque for the drive shaft is elastically transmitted to the rachet wheel when the guide bar is delivered between the rachet wheel and the chain. With this arrangement, it is always possible to smoothly transfer the guide bar between the rachet wheel and the chain without jamming of the apparatus.
